I had 3 virtual rounds for the interview, one each with the interviewer based in Hong Kong, London and new York. The interview experience was generally positive, with plenty of time given to me to clear any questions I had about the firm or position. All the 3 rounds were technical, with concepts surrounding Linux networking deepdives especially the TCP/IP stack and concepts like FIX or other common financial market data protocols.

I was rejected in the third round, with the interview loop lasting for 5 rounds in total. Since I am based in India, the interviews were often scheduled at odd times due to the interviewer's location, but it was manageable. Overall I had a good interview experience, and if I prepared better, I might have cleared it.
